Across
- 2. the subunit that serves as the building block of a polymer
- 3. an organelle in eukaryotic cells that serves as the site of cellular respiration; uses oxygen to break down organic molecules and synthesize ATP
- 5. a network of microtubules, microfilaments, and intermediate filaments that extend throughout the cytoplasm and serve a variety of mechanical, transport and signaling functions
- 8. a component of cytoskeleton that includes filaments intermediate in size between microtubules and microfilaments
- 9. an organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify, store, and route products of the ER and synthesize some products, notably noncellulose carbohydrates
Down
- 1. a membranous sac that helps move excess water out of certain freshwater protists
- 4. one of a family of closely related organelles that includes chloroplasts, chromoplasts, and amyloplasts. Plastids are found in cells of photosynthetic eukaryotes
- 6. the membrane at the boundary of every cell that acts as a selective barrier, regulating the cell's chemical composition
- 7. an extracellular glycoprotein secreted by animal cells that helps them attach to the extracellular matrix
- 10. a cellular extension of amoeboid cells used in moving and feeding
